For another example, if the adjacent UEs adopt different uplink and downlink configurations, uplink and downlink transmissions of the adjacent UEs may not be synchronized, which may cause the UE that is performing a downlink reception to be interfered by the UE that is performing an uplink transmission.

At present, the terminal device may measure energy of a receiving signal on a time-frequency resource.

It should be understood that a device having a communication function in a network/system in the embodiment of the present disclosure may be referred to as a communication device. The communication system 100 shown in FIG. 1 is taken as an example. The communication device may include a network device 110 and UE 120 which have communication functions. The network device 110 and the UE 120 may be the above-mentioned specific devices, and descriptions thereof are omitted here.

In addition, the character “/” herein generally indicates that front and back associated objects are in an “or” relationship.

In a wireless communication system, interference has always been a critical issue that plagues the terminal device. The interference to the terminal device may include Type 1 and Type 2. Taking FIG. 2 as an example, in the figure, UE1-1 and UE1-2 belong to a cell covered by gNB1, UE2-1 and UE2-2 belong to a cell covered by gNB2, and UE3-1 and UE3-2 belong to a cell covered by gNB3. If neighboring cells all use the same uplink and downlink configuration, when UE1-2 receives a downlink signal, other cells are also performing downlink signal transmission (if there is transmission), and there will be no uplink signal transmission. Therefore, UE1-2 It will only be interfered by signals sent by other gNBs, that is, Type1 interference; if relatively dynamic uplink and downlink configuration is supported, for example, a current service of UE3-2 has uploading data with large traffic, then gNB3 may configure more uplink resources for the transmission of UE3-2, when the uplink and downlink transmission directions of UE1-2 and UE3-2 are different, Type 2 interference may occur. That is, when UE1-2 is receiving the downlink data transmission, it is interfered by UE3-2 sending the uplink signal, and interference measurement for the Type 2 may be called cross-link interference (CLI) measurement.

The example given above is based on between the terminal and the terminal. CLI measurement is not only limited to between the terminal and the terminal, but can also be used in other similar situations, such as between the network device and network device.

It should be understood that the embodiments of the present disclosure may be applied to the above CLI measurement, and may also be applied to measurement for the above Type 1, and may also be applied to other interference measurements. Although the CLI measurement is mainly taken as an example in the embodiments of the present disclosure, those skilled in the art understand, this should not constitute a limit.

FIG. 3 shows a schematic block diagram of a wireless communication method 200 according to an embodiment of the present disclosure. As shown in FIG. 3, the method 200 may include some or all of the following content:

In S210, a terminal device determines a first frequency domain resource within a pre-configured resource block (RB) range.

In S220, the terminal device performs interference measurement or received energy measurement over the first frequency domain resource.

The first frequency domain resource or the resource block (RB) range is in term of a corresponding orthogonal frequency division multiplexing (OFDM) symbol. That is, the first frequency domain resource or the resource block (RB) range refers to a frequency domain resource on one or more OFDM symbols, rather than frequency domain resources on all times.

Specifically, the network device may configure the resource block (RB) range for the terminal device or pre-agree the resource block (RB) range for the terminal device by an agreement. For example, the network device may configure the terminal device with at least two of start RB information, end RB information, and information about the number of the RBs of the RB range. Alternatively, the resource block range may be a range of a bandwidth part (BWP). The terminal device may determine a frequency domain resource within the RB range to perform the interference measurement or the received energy measurement, for example, perform received signal strength indication (RSSI) measurement to obtain a RSSI value, where the RSSI value refers to a linear average value of a total received power obtained by the UE through measurement on certain OFDM symbols on a measurement time resource and resource elements configured in a measurement bandwidth.

For the terminal device, the pre-configured RB range may not completely be used for the interference measurement or the received energy measurement. The interference measurement or the received energy measurement is only performed over some of the frequency domain resources. If the other part of the frequency domain resources is used for normal signal transmission, the waste of frequency domain resources may be reduced, thereby improving the performance of terminal device.

The network device may also configure time domain information corresponding to the RB range. The time domain information may include, for example, at least two of start symbol indication information, end symbol indication information, and the number of symbols.

It should be noted that RB is a resource unit allocated for service channel resources, it may be one time slot in a time domain, twelve subcarriers in a frequency domain, and one resource element (RE) may be one subcarrier in in the frequency domain, that is, one RB may include twelve REs in the frequency domain. Generally, the RB may include two types, a virtual resource block (VRB) and a physical resource block (PRB). The VRB is a virtual RB. Resources are allocated according to the VRB, and then the VRB is mapped to the PRB.

The embodiments of the present disclosure may be applied to the above-mentioned CLI measurement. First, introduction of CLI and the necessity of CLI measurement will be briefly introduced.

On the terminal device, different services or application software have different requirements for an uplink data rate and a downlink data rate. For example, when watching a movie on a mobile phone, the downlink data rate is typically higher than the uplink data rate. In contrast, some services or application software (such as backing up local data to the cloud) often require the uplink data rate higher than the downlink data rate. For the same service or application software, different operations often have different requirements on the uplink and downlink data rates. For example, uploading videos for sharing requires a higher uplink data rate, while watching videos shared by friends requires a higher downlink data rate.

Based on situations of the above-mentioned actual service or application software, if the wireless network maintains fixed or semi-static uplink and downlink resource allocation (for example, fixed uplink and downlink slot configuration in the LTE/NR system), It may be impossible to optimally match the service transmission in a short period of time, resulting in inefficient use of resources, and the UE experience cannot be further improved.

In order to solve the above problems, a method of dynamically adjusting the uplink and downlink transmission directions (transmission resources) may be adopted. For example, the downlink data volume of the current cell or UE increases, the network may make more resources for downlink transmission (for example, make more slots for downlink transmission).

The NR system has indicated a flexible slot format. In one of the slots, some symbols are configured for downlink (D), some symbols are configured for being flexible (F), and some symbols are configured for uplink (U). Some configurations currently supported in the NR protocol are shown in table 1. Table 1 includes some slot formats. For example, in Format 20, first two symbols of a slot are configured as D, the last symbol is configured as U, and eleven symbols in the middle are configured as F.

TABLE 1 Slot formats for cyclic prefix Symbol number in a slot Slot format 0 1 2 3 4 5 6 7 8 9 10 11 12 13 0 D D D D D D D D D D D D D D 1 U U U U U U U U U U U U U U 2 F F F F F F F F F F F F F F 3 D D D D D D D D D D D D D F 4 D D D D D D D D D D D D F F 5 D D D D D D D D D D D F F F 6 D D D D D D D D D D F F F F 7 D D D D D D D D D F F F F F 8 F F F F F F F F F F F F F U 9 F F F F F F F F F F F F U U 10 F U U U U U U U U U U U U U 11 F F U U U U U U U U U U U U 12 F F F U U U U U U U U U U U 13 F F F F U U U U U U U U U U 14 F F F F F U U U U U U U U U 15 F F F F F F U U U U U U U U 16 D F F F F F F F F F F F F F 17 D D F F F F F F F F F F F F 18 D D D F F F F F F F F F F F 19 D F F F F F F F F F F F F U 20 D D F F F F F F F F F F F U 21 D D D F F F F F F F F F F U 22 D F F F F F F F F F F F U U 23 D D F F F F F F F F F F U U 24 D D D F F F F F F F F F U U 25 D F F F F F F F F F F U U U

If the cell changes the slot format relatively dynamically, or the base station changes the corresponding slot format for a certain UE or some UEs, CLI may occur. Alternatively, if the slot format does not change, CLI may also occur. For example, all symbols in one slot are configured as F, that is, format 2 in table 1. The gNB1 in FIG. 2 uses this slot for the downlink transmission of UE1-2, and gNB3 uses this slot for the uplink transmission of UE3-2, and CLI may also occur.

Therefore, it is necessary to perform the CLI measurement to control the interference caused by different uplink and downlink transmission directions and ensure the performance of the UE.

In the embodiments of the present disclosure, an overall process is as follows.

In step 1, the network device may send related configurations to the terminal device, for example, configuration of the measurement resource or configuration of a report value.

In step 2, the terminal device may perform a related measurement according to the measurement configuration, and report a measurement result to the network device according to the configuration of the report value.

In step 3, the network device may determine whether it is necessary to modify the uplink and downlink transmissions according to the received report information, so as to avoid interference to the terminal device.

Some of the above steps are optional, for example, the step 3. The network may not perform any processing when receiving the report information.

Optionally, the terminal device may receive first information of the network device, and the first information may be used for indicating at least one RB within the range of the RB, and then the terminal device may determine the first frequency domain resource according to the at least one RB indicated by the first information. Alternatively, the terminal device may not receive the first information, that is to say, the network device does not indicate the at least one RB within the RB range, then the terminal device may determine the first frequency domain resource according to the at least one RB (that is, at least one RB defaulted by the terminal device) within the RB range agreed by the protocol in advance.

Optionally, A RBs may be used as a group to group a certain frequency domain range. For example, the certain frequency domain range may be a part of the bandwidth of the system, or the entire bandwidth of the system, or a range of the bandwidth part (BWP), or other bandwidths that include the RB range, then the RB range may include one RB group or multiple RB groups. For example, the RB range may include one or more incomplete RB groups, as shown in FIG. 4a . The RB range may also include one or more complete RB groups, as shown in FIG. 4b . The first information may indicate at least one RB group, and the terminal device may determine the first frequency domain resource in combination with the RB range. If a certain RB group indicated by the first information is incomplete in the RB range, the first frequency domain resource may include the frequency domain resources in the RB group included in the RB range. Optionally, based on the foregoing grouping, the first information indicates a specific RB in a RB group, and the terminal device may determine the first frequency domain resource according to a frequency domain resource consists of the specific RB indicated by the first information in each RB group within the RB range. For example, as shown in FIG. 5, the entire frequency domain range includes 20 RBs. With 4 RBs as a group, it may be divided into 5 RB groups in total. The RB range may be 16 RBs in the middle of the entire frequency domain range. If the first information indicates a first one of the RBs in a RB group, then the frequency domain resource consists of the specific RB indicated by the first information in each RB group within the RB range includes the 3rd, 7th, 11th, and 15th RBs in the RB range. Optionally, based on the above grouping, the network device does not indicate a specific RB in a RB group to the terminal device, then the terminal device may determine the first frequency domain resource according to the specific RB (that is, a default RB by the terminal device) within the RB range that is pre-appointed by the protocol in each RB group. For example, the default RB in one RB group may be a first one of the RBs in the RB group. Similarly, the first frequency domain resource may be determined by the 3rd, 7th, 11th, and 15th RBs in the RB range shown in FIG. 5. Alternatively, the default RBs in one RB group may also include all RBs in one RB group.

Optionally, grouping may be performed only within the RB range, and each RB group may include the same or different number of RBs. For example, the number of RBs included in the first RB group and the last RB group may be smaller than the number of RBs included in the middle RB groups. The number of RBs included in the middle RB groups may be same. The grouping may be agreed in advance by the protocol or pre-configured by the network device. Similarly, the network device may send the first information to the terminal device, and the first information indicates at least one of the RB groups. Alternatively, grouping may be performed only within the RB range, and each RB group only includes the same number of RBs. The network device may send the first information to the terminal device, and the first information indicates a specific RB in a RB group.

Optionally, the foregoing grouping may also start from a common resource block 0, or the network device may also indicate the start RB of the grouping to the terminal device.

Optionally, the number of RBs included in one RB group, for example, the above-mentioned A may be agreed by the protocol and is a fixed value; or may also be agreed by the protocol and is related to the bandwidth range. For example, the number of RBs included in different bandwidths, and the number of RBs included in one RB group may also be different; or the number of RBs included in one RB group may be directly configured by the network device; or it may also be related to the RB range configured by the network device. For example, if the RB range indicated by the network includes X RBs, then one RB group may include X RBs. Or the number of RBs included in one RB group may also be a size of a resource block group (RBG). The size of the RBG may be as shown in Table 2.

TABLE 2 BWP size Configuration 1 Configuration 2  1-36 2 4 37-72 4 8  73-144 8 16 145-275 16 16

Optionally, the RB range may also be represented by a pattern. For example, the RB range may correspond to B patterns, and a combination of the B patterns may constitute the entire RB range. The network device may configure the B patterns for the terminal device in advance, or the B patterns may also be pre-agreed by the protocol and stored in the terminal device. The network device may send the first information to the terminal device, and the first information may indicate at least one of the patterns, and the terminal device may determine the first frequency domain resource according to the at least one pattern indicated by the first information within the RB range. For example, as shown in FIG. 6, the RB range includes 12 RBs, and the RB range corresponds to 4 patterns, and a shaded part in each pattern indicates that it may be used for the interference measurement or the received energy measurement. A combination of the shaded part of each of the four patterns may represent the entire RB range. The 1^(st), 5^(th) and 9^(th) RBs in pattern 1, the 2^(nd), 6^(th) and 10^(th) RBs in pattern 2, the 3^(rd), 7^(th) and 11^(th) RBs in pattern 3, and the 4^(th), 8^(th) and 12^(th) RBs in pattern 4 may be used for performing the interference measurement or the received energy measurement. If the first information indicates the pattern 1 and the pattern 3, the terminal device may determine the first frequency domain resource through the 1^(st), 3^(rd), 5^(th), 9^(th) and 11^(th) RBs within the RB range. It should be understood that the B patterns corresponding to the RB range may come from one or more pattern sets. As shown in FIG. 7, the RB range corresponds to 7 patterns, where patterns 1 to 4 are from one pattern set, patterns 5 and 6 are from one pattern set, and pattern 7 is a pattern set. Then the at least one pattern indicated by the first information may come from one pattern set or multiple pattern sets. For example, if the first information indicates patterns 1 to 3, then at least one pattern indicated by the first information belongs to the same pattern set. For another example, if the first information indicates pattern 2, pattern 5, and pattern 7, then the at least one pattern indicated by the first information belongs to different pattern sets.

It should be understood that the terminal device may use at least one RB within the RB range indicated by the first information or all frequency domain resources on at least one default RB within the RB range to perform the interference measurement or the received energy measurement. That is, the terminal device may determine the at least one RB within the RB range indicated by the first information or all frequency domain resources on the at least one default RB within the RB range as the first frequency domain resource. Alternatively, the terminal device may also determine the at least one RB within the RB range indicated by the first information or a part of the frequency domain resources in the at least one default RB in the RB range as the first frequency domain resource. For example, the terminal device may also combine the second information sent by the network device, where the second information is used for indicating a specific RE on an RB. In this case, the terminal device may determine the frequency domain resource consists of the specific RE on each RB in the at least one RB determined in the foregoing manner within the RB range as the first frequency domain resource. For example, the terminal device may combine the first information and the second information to determine the first frequency domain resource. That is, the terminal device may determine the frequency domain resource consists of the at least one RE indicated by the second information on each of the at least one RB indicated by the first information within the RB range as the first frequency domain resource.

For another example, the network device does not send the second information to the terminal device, and the terminal device may combine RBs on one RB agreed by the protocol (default). In this case, the terminal device may determine the frequency domain resource consists of the default REs on each of the at least one RB determined in the foregoing manner within the RB range as the first frequency domain resource. The default RE may be, for example, the first RE of each RB, or all REs on each RB (that is, 12 REs).

Optionally, the terminal device may also determine the first frequency domain resource only according to a specific RE on one RB or a default RE on one RB indicated by the second information. For example, the terminal device may determine the frequency domain resource consists of the specific RE or the default RE indicated by the second information on each RB within the entire RB range as the first frequency domain resource. In this case, it may also be considered that the first information indicates all RBs in the entire RB range.

Optionally, the RE combination in the RB may also be represented by a pattern. One pattern is used for indicating at least one RE that may be used for measurement by the terminal device. For example, one RB corresponds to D patterns, and a combination of the D patterns may constitute one RB. The network device may configure the D patterns for the terminal device in advance, or the D patterns may also be agreed upon by the protocol. The network device may send the second information to the terminal device, and the second information may indicate at least one pattern, then the terminal device may determine the frequency domain resource consists of the at least one pattern indicated by the second information on each of the at least one RB within the RB range determined in any of the foregoing manners as the first frequency domain resource. For example, as shown in FIG. 8, one RB corresponds to 12 patterns, and a combination of the shaded part in each pattern may represent the entire RB. Among them, the first RE in pattern 1, the second RE in pattern 2, the third RE in pattern 3, the fourth RE in pattern 4, the fifth RE in pattern 5, the sixth RE in pattern 6, the seventh RE in the pattern 7, the eighth RE in the pattern 8, the ninth RE in the pattern 9, the tenth RE in the pattern 10, the eleventh RE in the pattern 11 and the twelfth RE in pattern 12 may be used for the interference measurement or the received energy measurement. If the first information indicates patterns 2, 4, and 6, the terminal device may determine the frequency domain resource consists of the second, fourth, and sixth REs on each RB in the at least one RB determined in the foregoing manner within the RE range as the first frequency domain resource. Similarly, the D patterns corresponding to one RB may also come from one or more pattern sets. For details, please refer to the B patterns corresponding to the RB range, which is not repeated here for brevity.

Optionally, the network device may indicate the foregoing various information through a bitmap. For example, the first information may include a first bitmap, and each bit in the first bitmap corresponds to one RB group. And a value of each bit in the first bitmap represents a state of one RB group. For example, if the value is 0, it means that the RB group is unavailable, and if the value is 1, it means that the RB group is available. FIG. 9 shows states of 4 RB groups corresponding to the values [1 0 1 0] in the first bitmap, and the first RB group and the third RB group may be used for the interference measurement or the received signal measurement.

For another example, the first information may include a second bitmap, each bit in the second bitmap corresponds to one RB in one RB group, and a value of each bit in the second bitmap represents a state of one RB. For example, if the value is 0, it means that the RB is not available, and if the value is 1, it means that the RB is available. FIG. 10 shows states of the 4 RBs included in one RB group corresponding to the second bitmap with values [1 0 0 0] and [1 0 1 0], where [1 0 0 0] represents the first RB in one RB group is available, [1 0 1 0] indicates that the first and third RBs in one RB group are available.

For another example, the first information may include a third bitmap, each bit in the third bitmap may correspond to one pattern, and a value of each bit in the third bitmap represents a state of one pattern. For example, if the value is 0, it means that the pattern is not available, and if the value is 1, it means that the pattern is available. FIG. 11 shows states of 3 patterns corresponding to the values [1 1 1] of the third bitmap, where the 3 patterns are all available, and the combined frequency domain resources may be the entire RB range.

For another example, the second information may include a fourth bitmap, each bit in the fourth bitmap may correspond to one pattern, and a value of each bit in the fourth bitmap represents a state of one pattern. For example, if the value is 0, it means that the pattern is not available, and if the value is 1, it means that the pattern is available. FIG. 12 shows states of 4 patterns corresponding to the values [1 0 1 0] of the fourth bitmap, and the combined frequency domain resources may include the 1^(st), 3^(rd), 5^(th), 7^(th), 9^(th) and 11^(th) REs.

Optionally, the network device may not use the bitmap to indicate the above information, and may also directly indicate the information. For example, as shown in FIG. 7, there are 7 patterns in total, and the network device may indicate one of them by 3 bits. The grouping is similar, and no too much description is given here.

Optionally, the network device may send third information to the terminal device, where the third information is used for indicating at least two of start RB information of the RB range, end RB information of the RB range, and information about the number of RBs included in the RB range. The terminal device may determine the RB range according to the third information. The start RB indicated by the third information may be included in the RB range or outside the RB range, and the end RB indicated by the third information may also be included in the RB range or outside the RB range.

Optionally, the network device may determine the range of the BWP as the RB range. In other words, the terminal device can determine the RB range according to the configuration of the BWP.

The above various information may be carried in various high layer or physical layer signaling such as a radio resource control (RRC), a MAC signaling or a downlink control information (DCI) signaling. The above-mentioned information may be sent separately or combined and sent together. For example, the first information may be sent together with the second information, the second information may be sent together with the third information, or the first information, the second information and the third information may be sent together.

Optionally, the terminal device may perform the interference measurement or the received energy measurement over the first frequency domain resource determined in the above manner to obtain a measurement value, for example, a RSSI value or a reference signal received power (RSRP) value etc. The terminal device may directly report the measurement value to the network device, or may report the value used for indicating the size of the measurement value to the network device, thereby reducing signaling overhead.

For example, the terminal device needs to determine the report value to be sent to the network device according to the RSSI value obtained by the measurement. It may be divided into multiple measurement intervals according to the size of the RSSI value, and each measurement interval corresponds to a report value. A mapping relationship between the multiple measurement intervals and the report values may be as shown in Table 3.

TABLE 3 Mapping relationship 1 Report value Result of measurement Unit Report value 0 RSSI < −100 dBm Report value 1 −100 ≤ RSSI < −99 dBm Report value 2 −99 ≤ RSSI < −98 dBm . . . . . . . . . Report value 74 −27 ≤ RSSI < −26 dBm Report value 75 −26 ≤ RSSI < −25 dBm Report value 76 −25 ≤ RSSI dBm

In Table 3, the measurement interval may be divided at equal intervals. Optionally, a measurement interval to which a minimum RSSI value belongs and a measurement interval to which a maximum RSSI value belongs may be excluded. The measurement interval may use 1 dBm as an interval to improve reporting accuracy, or use an interval greater than or equal to 2 dBm to reduce signaling overhead. For example, if the measured RSSI value is −99.5, the terminal device can report the report value 0 to the network device. For another example, if the measured RSSI value is −24, the terminal device can report the report value 76 to the network device. The interval of the measurement interval may be configured by the network device.

Optionally, a form of the report value may be agreed upon by the agreement, and an order of the report value in Table 3 may also vary. For example, RSSI<−100 and −25 RSSI can correspond to report value 0 and report value 1, or RSSI<100 and −25 RSSI can also correspond to report value 75 and report value 76, as long as one measurement interval corresponds to one report value.

Optionally, critical values of two adjacent measurement intervals in Table 3 may include any one of the two measurement intervals. For example, −27 RSSI<−26 and −26≤RSSI<−25 may be changed to −27≤RSSI≤−26 and −26<RSSI<−25.

Optionally, the upper boundary value −25 and the lower boundary value −100 in Table 3 may be adjusted, that is, may be increased or decreased, and two or one of the upper boundary value and the lower boundary value may be configured by the network device. The network device can flexibly determine the dynamic range according to the application scenario. For example, if the range in Table 3 is expanded, a larger range of measurement values may be reported, and if the range in Table 3 is reduced, the transmission resources required for reporting may be saved.

Optionally, the multiple measurement intervals may also be divided by at least one threshold. For example, the network device may configure one or more thresholds, or one or more thresholds may be agreed upon by the protocol, and the RSSI value is divided into multiple intervals according to the one or more thresholds. Table 4 shows another mapping relationship of multiple measurement intervals and multiple report values, where thre, thre+x, thre+2x, and thre+3x may be considered as thresholds. Thre may also be considered as a threshold value, and x may be an interval agreed upon by the protocol or configured by the network device.

TABLE 4 Mapping relationship 2 Report value Result of measurement Unit Report value 0 thre ≤ RSSI < thre + x dBm Report value 1 thre + x ≤ RSSI < thre + 2x dBm Report value 2 thre + 2x ≤ RSSI < thre + 3x dBm . . . . . . . . . Report value n −25 ≤ RSSI dBm

Specifically, when there is only one threshold value, the RSSI value may be divided into two measurement intervals, one is a measurement interval greater than or equal to the threshold value, the other is a measurement interval less than the threshold value. The measurement interval greater than or equal to the threshold value corresponds to one report value, and the measurement interval less than the threshold value corresponds to another report value. Or, only when the measured value is greater than the threshold value, it is reported to the network device, for example, the corresponding report value is reported. This may reduce the overhead of reporting resources.

The terminal device may also take a threshold value thre as a starting value, and determine the mapping relationship according to the interval x agreed by the protocol or configured by the network device, as shown in Table 4. The other boundary value may be assumed to be −25, or it may be thre+N*x, and N may also be a positive integer agreed by the protocol or configured by the network device.

Optionally, an order of report values in Table 4 may also vary. Critical values of two adjacent measurement intervals in Table 4 may also include any one of the two measurement intervals.

Optionally, the terminal device may send the foregoing determined report value to the network device through the RRC signaling, the MAC control element (CE) signaling, or the physical uplink control channel (PUCCH).

After receiving the report value of the terminal device, the network device may the uplink and downlink transmission mode according to a size of the measured value indicated by the report value. For example, if the RSSI value reported by the UE is large, the network device may perform scheduling or configuration, to avoid interference caused by other devices to the UE; if the RSSI value reported by the UE is small, the network device may schedule the resource corresponding to the UE without affecting the performance of the UE.
